Zeytlenok Cand Mod Sci Moscow Many of the ?rimary encephalitic and other infectious diseases of the nervous system are caused by virus. In the last 12 years, Soviet scientists have made great strides in solving this relationshil.. Progress in virological rese4rch has been ride possible by contributions of virologists, neuropath- o'aete, psychiatrists, as well as by parasitological and epidemiological institutions and clinics of infectious diseases. New achievements in neuropathy were discussed at the Fourth Session of the Institute of Ncurology, Academy of Medical Sciences USSR. Representatives of 37 Republic and Oblast centers attended. Among reports were those on tick- betss encephalitis, chorio-encephalitic (psychosensory neuro-infect!an), chorio- sen1 itis, hemorrhagic fever, and papers were presented on undeterminei tioftn of nervous systems. Prof M. P. Chumakov, Corresponding Member, Academy of Medical Sciences USE, claims that in spite of various forms of tick-borne encephalit+.q there is one fact common to all cases: studies conducted by virologists and immunol- o gists resulted in conclusion that all strains isolated from various cases belonged to one virus. This claim was supported by clinical, pathomorphologi- cal and experimental data. Prof L. A. Zil'ber, Active Member, Academy of Medical Sciences USSR, dis- agreed with Prof Chumakov: Zil'ber supported the fact which clinicists have 1 ma nnnteniwd. t}wt thwrw vwrw varlova c11nirtn1 forma of tick-borne encechalitla in the different PPgions of the USSR.'

The causative agent of chorio-encephalitis seems to be a filtrable virus. Chcrio-encephalitis has been studied for only about 18 months, but !n that short time Soviet scientists have learned much about the disease. Reports by 50X1-HUM, They also proposed to find improved methods for the etiological diagnosis of tick-borne encephalitis. (sulphur therapy ), and Prof A. V. Pehenichnov (sulphur prophylaxis), showed the valua of the indicated therapy.

However, there is great variation in the nosologic boundary, It was concluded that this form of encephalitis is completely different from the known forms of encephalitis and meningitis, including the so-called Econamo's encephalitis, and is a new type of disease. Various ideas were submitted regarding pathogeneeie of tb a disease. Cbumakov'e hypothesis, supported by clinieists and neuropatbolc.jista, is that patients afflicted undergo a degeneration of the vascular plexus in the cranial sinus (choroid plexus). This results in increased spinal fluid pressure. In acme cases there is edema of the white matter of the brain and disruption of function of the psychoseneory sphere. developed a vaccine for this disease.
